I have a Compaq NC6000 laptop. I had a bad motherboard so I changed it to a different mother board (WORKING). After installing I turned it on and it went threw a bunch of numbers. Once that was done a window ask if I WANT to do the following. I think it said to cancel, set up computer, or save setting. I choose set up computer. This OPENED a new window for setting up the computer. I think it was the DIOS (spelling) window for the computer. I have seen it before when I had to put a new hard drive in. I just exit out of this window. Shortly after that the computer screen went BLANK. The lights on the hard drive and multibay drive were flashing with a beep (if I remember right). Same time the light flashed on it beeped. How many beeps I do not remember. Did not know it was a code. Now all it does are both lights are continuously on. I have played with plugging in the power with the battery to any possible way with a power source. We I do this and turn on the computer nothing but lights on and sometimes the FAN would turn on. Again this is from different start ups things would happen. Lost!!!!
